    The diffusion coefficient is a measure of quality designed to be used by producers and users of surfaces that, either deliberately or accidentally, diffuse sound. It is also intended for use when needed by developers and users of geometric room acoustic models. The diffusion coefficient is not intended, however, to be blindly used as an input to current diffusion …

    High values of the diffusion coefficient indicate that a surface scatters sound uniformly to all receivers. Low values tell us that a surface is concentrating reflected energy in one direction. The higher the coefficient at a particular frequency, the more effectively sound is …

    diffusion coefficient, D = (see Lecture 3), which has/RT an SI unit of m²/s (length²/time). Apparently, D is a proportionality constant between the diffusion flux and the gradient in the concentration of the diffusing species, and D is dependent on both temperature and pressure.

DIFFUSION COEFFICIENT

    https://thermopedia.com/content/696/
    Diffusion coefficient is the proportionality factor D in Fick's law (see Diffusion) by which the mass of a substance dM diffusing in time dt through the surface dF normal to the diffusion direction is proportional to the concentration gradient grad c of this substance: dM = −D grad c dF dt. Hence, physically, the diffusion coefficient implies that the mass of the substance diffuses through a ...

    The diffusion coefficient in p -doped Si is given by, (4.13) D B, Si ( p) = D i 1 + β p / n i 1 + β, where Di is the intrinsic diffusivity, p is the density of holes, and ni is the intrinsic carrier density. Enhancement of the diffusion coefficient at extrinsic doping is determined by the parameter β.

    Diffusion coefficients are one of the very fundamental kinds of data needed for many metallurgical process developments and for materials design (see Diffusion in Solids).Since many binary diffusion couples are created in diffusion multiples, diffusion coefficients can be readily extracted from the binary diffusion profiles using Boltzmann–Matano analysis or other …
